The molecular weight of a gas that has a density of 7.10 g/L at 25.0 °C and 1.00 atm pressure is G/mol. A) 28.0 B) 174 C) 5.75 × 10^-³ D) 6.85 × 10^-² E) 14.6

Question

Quizplus · Accepted Answer

Using the ideal gas law, PV = nRT, and the relationship between moles and molecular weight, the molecular weight can be calculated as (density * R * T) / P. Substituting the given values, the molecular weight is approximately 174 g/mol.
